Letters Patent No. 95,07 3, `(lated September 21, 1869.

. IMPROVEMENT IN WHEAT-DRILLS.

The Schedule referred to in these Letters Patent and making part of thesame To all whom it may concern:

-and testament of said ROBERT G. BLU r, deceased,

and'HIRAM BLUNT, all of the place aforesaid, do hereby declare `theiollowing to be a full and truc descrip- `tien thereof, reference beinghad to the accompanying drnvings, andto the letters of reference markedthere- In the construction of the said wheat-drill, the seedbox restsupon the cutters or plows, andthe draught` team is attached to the`frame-work formed by said parts.

In ,the rear of said frame is hinged a second frame,

Ysupl'iorted also upon covering-rollers in said trarne.

. For the purpose of adjusting'the dcptlrto which the cutters enter, thenature of our invention is in the arrangement of a hinged seat and afoot-rest in snchwise that the opcratin or driver upon the seat shall-beable to gauge the vcutter-depth by the use of foot-power to support moreor less of the weight of the feed-box and its frame uponthe rollers;

Secondly, to form a more perfect feeding-device, the

nature of said invention is in the arrangement of a seed-feeding screwwith the seed-box and seed-tubes,

; n"thc spcciiic manner hereinafter described.

To enable those herein skilled to'inalte and use our said improvements,we will now lnorc fully describe thesamc, referring herein to theaccolnpanying-v F-igure l as a sectional elevation, to Figure 2 as a topview, and

Figure 3 asa Vrcar end view of the drill, in such form as to exhibit thcseparateiliaturcs of this invention. y

`Vile arrange the seed-box A in about the usual forni for containing thegrain to be planted.

Connected with the bottoni thereof is the standard B, which supportsthc`rear end ofthe cutter C or plow.

`The forward end of said eut-ter is held upon the transverse bar Aconnected with the seed-box traine.

' The tongue 1) is attached to the box A, and passes overthe vbar A',connecting'suitably therewith.

'lvhe cutters or plows here used will be of suit-able form to open afurrow for the grain, being shaped generally as indicated iu thefigures. f

The seed-box A has the. bottoni board u, in which are the seed-openingso leading to the feed-boxes Ill ll". `Said boxes are arranged double, asat E, ex-

cept when an odd cutter or seed-tube is-to be snpported. l

Usually there are vseven seed-tubes; hence, in our A said drill, therewill generally' bc three double boxes E,

opening in the said feedeboxes, and acting to deposit .the grain inthefurrow made by the cutters.

In the double boxes E the screws f are then right and left inclined, asindicated in fig. 2, thus giving t-hc proper space between the furrowsand sown grain. v v

In order that the feed-screws f shall noi-clog by straw, or dust, or.other impurities, we arrange at the rear of the Vboxes E E' the. sildese, which may be readily raised, thus affording ingress to cleanse thesaid boxes when desirable. I

To the box-frame A, we hinge the bars H, which are joined at their rearends by the cross-piece I.

Said bars 1I sustain the roller-shaft K, on which are arrangedtherollers L, being placed to cover the furrow of each cutter' C. Y

On said shaft K are furthermore the pulleys lc, oonnecting, by belts orbands la', with 'pulleysf upon the screw-shaft F, so that the movementofthe roller-shaft lIs. causes the feed-screws to revolve.

Upon'the bar I, we arrange, by a hinged joint, the seatstandzud M,connecting withl the. seat-board N, this being again hinged, as shown inlie. l, with the front standard O, secured to the seed-box A.

Beneath the seat-board, and within reach of the fee-t of the operator,we arrange the foot-rest I), connected securely to the seed-box A.

The driver, sit-ting upon the larard N, may then, by pressing thefoot-rest I down, raise thcseed-box frame and its cutters C to a higherangular position, or, by releasing pressure, vho may drop the said partsto a lower angular position, thereby giving lthe cutters a greater orless tendency to ent-er the ground, and gauging their depth. At thcsaine. time, as, by said construction, the weight of the driver is wellbalanced upon the rollers I, the draughtof the nlachine is much reduced,and the operation of covering the grain in the furrow is made all themore effective. A Y

Having thus fully described the said invention,-

What is claimed, is- Y 1. The seed-box A and feed-boxes E E', whenarranged with slides e and the feed-screws f,..substan tially as setforth. y

2. The hinged support given to the driver upon the roller-frame, and thefoot-rest connected wit-li the seed box frame, when combined to beoperated substantially as set forth.

In witness whereof, we ,have hereunto set our hands,

in the presence of HI'RAM BLUNT, MARY J, BLUNT, Executors of the lastwill and. testament of Robert C'. Blu-nt, deceased.
